Abstract

PURPOSE:To realize the effective use of facility space and efficient maintenance while preventing a system from being down due to a partial power supply fault by decentralizing and installing control signal transmitting modulators in display measuring receivers of a power transmission system. CONSTITUTION:Control information, supplied from control table 1 to control transmitter 3, is coded by control transmitting circuits 7A and 7B, modulated by signal transmitting modulators 8A-8N installed in display measuring receivers 5, and then sent out to transmission line 20. Signals propagating through transmission line 20 are supplied to control signal receiving circuits 10A-10N by way of signal transmitting demodulators 9A-9N of remote supervisory, controllers 6 for a spot to be controlled. As a result, only circuit 10 at a spot to be controlled corresponding to the control signal operates to control an equipment at the corresponding controlled spot.
